COKE AND eas ovEN.

To all whom t may concern: i

Be it known that ll, DANIEL M. RUGG, a b

citizen of the United States, resident of Cleveland, county of Cuyahoga,and" State invented new and useful Improvements in Coke and Gas Ovens,of which the following is a specification,` the principle of theinvention being herein explained and the best mode in which ll have il@contemplated applying that principle, so as to `distinguish it' fromother inventions.

fr* My invention relates to apparatus for the production of gas andcoke.

The object of my invention is to provide an oven structure which may beused in connection with a fuel gas supply which, as well as the air,will require preheating, or `in which a coke oven gas which needs nopreheatingmay be used in connection with an airsupply suitablypreheated.

. The .sald invention consists of means Ihereinafter fully described andparticularly set forth in the claims.

he annexed drawings and description 'set forth in detail embodying mylit the following certain means invention, the disclosed means, however,constituting but one of various forms in which the principle of tlieinvention may be employed. In said annexed drawings: Figure lrepresentsa fragmentary longitudinal vertical section of a gas oven embodying myinvention and taken upon the planes indicated by lines I--I in Fig. 2.

ig. 2 represents a fragmentary transverse section taken through theheating units and uponl the planes indicated by lines IIs- Ill in Figs.1 and 3.

Fig. 3 representsa fragmentary horizon-- tal section taken upon theplane indicated by lines III- HL in Fig. 2.

. l Fig. 4 represents a broken horizontal section taken in` the planesindicated by the V.lines IV-IV,`vlFig. 1. at The illustrated embodimentof my invention comprises the usual masonry structure and auxiliaryparts forming a Iplurality of parallel' coking chambers l, 1, ig. 3.Between each two adjacent cokin chambers is a series of heating units 2,2. ach of these heating units consists of two vertical chambers 3 and 4separated from each other at the bottom' and connected at ,fthe to asshown inFig. 1. Each heating unit o any till ' tt given series isindependent of every .other of Specification of Letters Patent. IApplication tiled August 30,

such series, being separated from each other ythe vertical walls `5.

Below these coking chambers `and series of heating-,units is a pluralityof regenerators 6, `6, arranged in pairs of separate and lndependentsections 7, 7. The bottoms of alternate regenerator pairs 6` communicatewith two suitable ducts 8 and 8f by means of 1, which act alternately asoutletsfor waste gases in the usualmanner, as will be readily understoodby those skilled in the art.

One of the regenerators 7 of each regenerator pair 6 is connected withone of the combustion chambers of two heating units located uponopposite sides of the cokingl chamber' located immediately above suchregenerator pair, by means of passages 10, 10, and the other regenerator7 of the same pair 6 of regenerators is also connected with the same twochambers of these same two units by means of thepassages 11, 11. Thechambers of anyone unit are thus connected with regenerators locatedupon opposite sides of the vertical median plane of the said units. Aconstruction is thus provided which permits the reversal of thedirection of flow of the gases, whereby the regenerator may bealternately heated' by the waste gases, and then such heat used forheatingsnch gaseous 85 products as may subsequently be caused to passtherethrough.

It will thus be noted that the apparatus comprises the combination of aplurality of coking chambers, a plurality of heating 9G units, thecoking chambers and the heating unit series occurring alternately withreference to each other in the oven structure, each unit comprising twochambers, a plurality of pairs of regenerators each consist# ing of twoseparate and independent regenerators, connections between saidregenerators and hea-ting units such that gases may be passed throughalternatelyl occurring regenerators and lthrough all the heating units10.0 and then from the latter out through the remaining regenerators,and also in the reverse of such described direction; each such chamberbeing connected with a pair 7, 7, of regenerators and each regeneratorof such pair 105 being connected with two such chambers.

lOne of the chambers, therefore, constitutes a combustion chamber whilethe gas is traveling in one direction and the other chamber connectedtherewith forms merely 110 an outlet duct for the gases of combustionduring such period. When the gases are traveling in the oppositedirection, the other of said chambers forms a combustion chamlrequiringpreheating, the above-described apparatus is used and operated asfollows:

One regenerator 7 of alternately occurring pairs 6 is connected withlthe atmosphere through the flue 8 and the other regenerator of each ofthese pairs of regenerators is connected by any suitable means with thesource of cold fuel gas supply. vThe remain-A ing regenerators areconnected with the other of the waste gas flues. are now passed upwardlythrough the firstnamed regenerator sections and emerge from the passages10 and 11 where they are mixed and burned in the various combustionchambers immediately connected with those passages whence they passdownwardly through the other chambers of the heating units and outthrough the passages 10 and 11 thereof which act as outlets, into thesaid remaining regenerators, thus heating the checkerwork of the latter.The operation now being reversed, the pairs of regenera- 1 tors whichwere previously heated are now respectively used as air and gas heatingdevices, and the first-named regenerators are heated, as will be readilyunderstood, by the waste gases.

In addition to the above-described elements of the device, however, Ialso supply a separate and independent series of connections consistingof pipes 12 and 13 running beneath the heating units, pipes 12 beingprovided with a plurality of burners or gas nozzles 14, discharging intoalternately occurring combustion chambers of any given series of heatingunits, and pipes 13 being similarly provided with gas burners or gasguns discharging into the remaining combustion chambers as shown in Fig.3. These pipes are of course all'connected with a common supply,suitable valves (not shown) being provided for the re uired control aswill be understood.

'7hen a gas requiring no preheating is used, it is supplied to thecombustion chambers by4 means of these pipes 12 and 13 and when this isdone, both regenerators 7 7, of

Air and gas i chambers of each heating unit acts asa combustion chamberat any one time. In other respects the apparatus operates as before, thesame reversal being resorted to as will be understood.

From the above description it will appear that the construction which Ihave provided lends itself readily for use in connection with either asupply of gas requiring preheating or not, with the attendant economicaladvantages, which will be readily understood by those skilled in theart.

What I claim is:

1. In apparatus for the production of gas and coke, the combination of acoking chamber; heating units respectively located upon opposite sidesof said chamber and each consisting of two connected combustionchambers; a pair of regenerator sections, one of said combustionchambers of each such heating unit being provided with an outlet; ductsarranged to connect each of theother chambers of said heating units witheach of said regenerator sections; and means independent of 'said ductsfor introducing fuelv gas into said last-named combustion chamers.

2. In apparatus for the production of gas and coke, the combination of acoking cham ber; heating units upon opposite sides of said c-hamber andeach consisting of two connected combustion chambers; a pair ofregenerator sections, one of said combustion chambers of each suchheating unit being provided with a pair of outlets; ducts arrangedto-connect each of the other chambers of said heating unit with each ofsaid regenerator sections; two additional pairs of regenerators, therespective pairs of outlets arranged to connect with the respectivepairs of said two additional pairs of re generators; and meansindependent of said ducts for introducin named combustion c ambers.
